Struct ResizeArgs 

pub struct ResizeArgs {
    pub devid: Option<u64>,
    pub amount: ResizeAmount,
}

Arguments for a resize operation.

devid selects which device within the filesystem to resize. When None, the kernel defaults to device ID 1 (the first device).

Fields

devid: Option<u64>

Device within the filesystem to resize, identified by btrfs device ID. When None, the kernel defaults to device ID 1 (the first device).

amount: ResizeAmount

How much to grow, shrink, or set the device size to.

Implementations

impl ResizeArgs

pub fn new(amount: ResizeAmount) -> Self

Create a new ResizeArgs targeting the default device (ID 1) with the given resize amount.

pub fn with_devid(self, devid: u64) -> Self

Set the target device ID for the resize operation.

Trait Implementations

impl Clone for ResizeArgs

fn clone(&self) -> ResizeArgs

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ResizeArgs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ResizeArgs

fn eq(&self, other: &ResizeArgs) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
